LID FOR ICE CREAM CABINETS AND THE LIKE Filed Oct. 26, 1951 Patented Oct. 15, 1935 UNITED STATES PATENT OFFICE Julius Moss, Brooklyn, N. Y.

Application October 26, 1931, Serial No. 571,089

3 Claims.

This invention relates to improvements in lids for ice-cream cabinets and. the like.

Lids for ice-cream cabinets conventional-1y comprise a slab of heat-insulating material such as cork, sealed up between sheet metal top and bottom members and within a frame or rim, sometimes called a spacing member. An example of this general type of lid will be found in copending application, Serial Number 147,066 of 10 Victor J. Moss.

In my copending application, Serial Number 566,982 filed-October 5, 1931, I described a-method by which I am enabled to produce a construction of lid in which the sheet-metal top member will have an airtight and moisture proof connection with the rim so that the lid maybe absolutely clean and free from odors .and will be so securely fastened to the rim or frame that it will not .become loosened or separated under the rough 9 usage usually encountered; to provide a lid construction in which the outer sheet-metal top member will have adjacent to its marginal :edge an integrally-formed bearing portion and an integrally-formed fastening flange having a secure locking engagement with the inner wall of the rim and preferably having a secure interlocking engagement with an internal shoulder formed on the rim.

In conventional lids, the bottom lidand handle are fastened in place by perforating the bottom lid at its center and passing a screw therethrough which connects with .the lid handle which is mounted on the top member and one of the :objects vof my present invention is to .produce an air-tight and moisture-proof connection .of the bottom member with the rim anda more effective sealing of the heat-insulating material within the lid between the topand bottom members by eliminating the perforation which admits air and moisture to the interior of the lid, thus detracting from its insulating properties, and also further improve the heat insulating qualities byeliminating the use of the screw extending through the insulation and between the top and bottom of the lid, which screw serves as a metallic tem perature transmitter to transmit temperature from the bottom to the top of the lid or vice versa. My present invention, furthermore, constitutes an improvement in lid constructions by which the sheet metal bottom member will be so securely fastened to the rim or spacer around its edges that this bottom member may not only be made imperforate with the screw-fastening element which conventionally passes centrally through 53". the said bottom member eliminated, .but the .en-

tire lid. construction will be made more rigid, stronger and more durable.

With these and other objects in view, the invention comprises the combination of members 7 and arrangement of parts so combined as to co- 5 act and co-operate with each other in the performance of the functions and the accomplishment of the results herein contemplated, and comprises in one of its adaptations the species orpreferred form illustrated in the accompanying 1o drawing, in which:-

Fig. 1 is a vertical section, partly in elevation through an assembled lid embodying my invennon;

Fig. 2 is a diassembled view in vertical section 15 of the principal elements shown in Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 1, looking in the direction of the arrow; and

Figs. ,4 and 5 are fragmentary views of a rim portion and bottom member showing a modified 20 method of connection thereof.

Referring now to the drawing which illustrates a preferred embodiment of my invention, and shows a construction of a cabinet lid for icecream cabinets, indicates a frame member or 5 spacing element, which, in the embodiment shown, comprises the rim of the cabinet lid. In said embodiment, the frame member or rim l surrounds a block slab or disc 2 of cork or similar material having high heat-insulating 30" properties or qualities, and said slab or disc 2 is, as shown, interposed between top and bottom members 3 and 1 formed of sheet metal and spaced from each other by .said frame member or rim, 1,.

In the embodiment of my invention illustrated, the rim or frame member vl may comprise an annular ring having its body composed of rubber or other suitable material. The outer surface I of said rim, is, as illustrated, bevelled to fit .an 0 opening in ,an ice-cream cabinet (not shown) and is conventionally provided with an outwardly projecting flange Ieof flexible rubber adapted to engage with the edge of such opening.

In accordance with the invention of my former 5 application, Serial No. 566,982, filed October 5, 1931, and the preferred embodiment of my present invention, the inner surface l of the rim is provided with an annularinwardly-disposed radially-projecting shoulder 1 and the sheet-metal 50' top member 3 has a disc-shaped body portion covering the space surrounded by the rim and has a portion adjacent to its marginal edge folded inwardly to provide an integral inwardly-disposed seat portion 3' adapted to seat upon the 5 ing of the heat-insulating material within the lid upper wall or face of the rim and of said shoulder l and. said edge portion is again folded to provide an integral fastening flange 3 having an' intermediate portion abutting against the inner surface of the said shoulder I and an edge portion 3 extending beyond said shoulder andhaving a fold outwardly to engage the bottom surface I of said shoulder. As illustrated, the edges of the flange portion 3 are folded down beneath said shoulder as shown in Figs. 1 and 2. The formation of the .seat and flange, as shown, may be accomplished by suitable dies. This operation of folding down the flange portionbeneath the shoulder is preferably accomplished by the use of a suitable die after the top member with the flange in straight position, as shown in Fig. 2, has been applied to the rim. The top'member may thus be securely and firmly locked to the rim, and when the top member and its perimetric flange is properly fitted to the rim, the action of the last-mentioneddie will cause a tightening of the flanges on the shoulder and produce a tightjoint and a sealing of the metal with the material of the rim. This connection will be strong and durable and capable of withstanding very rough usage without becoming loose or separated from the rim and said joint, due to the integral character thereof and due to the fact that it is entirely unslitted, and continuous around the perimetric edge thereof will cause a hermetic, air-tight sealing of the joint between the rim and top member and this continuous flange will also increase the strength and stiffen or reinforce the construction of the top member and of the lid.

In conventional lids, the bottom lid and handle are fastened in place by perforating the bottom lid at its center and passing a screw therethrough which connects with the lid handle which is mounted on the top member and my present invention produces a more effective seal-.

between the top and bottom members by eliminating the perforation which admits air and moisture to the interior of the lid, thus detracting from its insulating properties, and also, I further improve the heat insulating qualities by eliminating the use of the screwextending through the insulation and between the top and bottom of the lid, which screw serves as a metallic temperature transmitter to transmit temperature from the bottom to the top of the lid or vice Vera.

My present invention, furthermore, constitutes an improvement in lid constructions by which the sheet metal bottom member will be so se-v curely fastened to the rim or spacer around its edges that this bottom member may not only be made imperforate with the screw-fastening element which conventionally passes centrally through said bottom member eliminated, but the entire lid construction will bemade more rigid,

stronger and more durable.

By my present invention, I provide an imperforate bottom member I and fasten the handle 9 to the top member, and inorder to provide a rigid base for the handle, I preferably provide a reinforcing disc lll registering with the body portion of the top member and also provide a washer member I I, through both of which a screw or bolt I2 is passed into the handle 9, which is provided with an internally screw threaded socket 9', with which the threads 8' of the bolt 8 intermesh, it being understood thatthe handle is to be pro- ,vided with a square bottom portion 9*- which fits into a square aperture 3 in' the sheet metal top memberso as to prevent the handle from turnof cork preferably embedded at the side abutting 5 the top member in an asphaltic or hydro-carbon tarry substance 4 which is adapted to harden and providea seal between the cork and the parts of the said top member.

In the embodiment shown, a spacing and reinforcing block 5 is arranged centrally in the slab of cork, a layer of hot asphaltic or hydro-carbon tarry substance 6 is applied so as to overlie the embedded cork slab and the edges of the rim. The sheet-metal bottom plate 1 which has an imperforate disc-shaped body portion 1 is provided with an integral fastening flange having an intermediate portion 1 adapted to abut against an external inclined portion l of the rim and is provided with a perimetric edge flange l adapted 20 to be inserted within and form a tight joint with a groove I in the external edge of the rim l. A bottom plate having the flanges I and l may be applied to the rim by pressing the same down over the edge of the rim and suitable dies may be employed for this purpose if desired.

In Figs. 4 and 5, I have shown a construction in which the bottom plate is applied to the rim with the flange 1, its edge portion l extending beyond a shoulder I in the rim and the edge portion I is then, by spinning, crimping or by any suitable dies bent inwardly to engage the said shoulder l As many changes could be made in the above construction and many apparently Widely different embodiments of this invention could be made without departing from the scope thereof;

it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and 0 not in a limiting sense.

Having described my invention, I claim:-

1. A lid for ice-cream cabinets, comprising, in combination, an annular rim member composed of a single piece of material and having adjacent to 45 the bottom edge a perimetric groove, a separable imperforate bottom member composed of a single piece, having a body portion, circular in conformation, and an inwardly-directed edge flange adapted to be sprung into locking engagement with the said perimetric groove in the rim portion, a separable top member connectible with the opposite side of said annular rim to close the same and an insulating filler within the space enclosed by said top and bottom members. 55
